Abstract

This disclosure relates to the construction of butterfly valves of the type used for controlling fluid flow and, more particularly, to a seal for use in sealing the periphery of the closure member of such valves. Further, the seal disclosed herein is loaded by the pressure of the fluid being handled, to enhance the tightness of the seal.
